Facile Ionic Liquid-Mediated, Efficient Microwave-Assisted One-Pot Green Synthesis of Privileged Linear and Angular Spirochromone Conjugates

Background: Over a decade, a number of papers have been published on the usage of ionic liquids (ILs) and Microwave-Assisted Organic Synthesis (MAOS), which displayed their benefits with respect to the conventional synthetic procedures, for current generation of fast, efficient and environmental friendly synthetic methodologies. The aim of the present study is the synthesis of linear and angular spirochromanone derivatives using microwave irradiation with the IL. As the microwave assisted organic synthesis (MAOS) with IL as a solvent is environmental friendly and non-volatile, therefore it allows simple separation and catalyst recycling. Keywords: Conventional heating, ionic liquid, kabbe condensation, microwave irradiation, spirochromanone.
